The London correspondent of the New York Time saya : This has been a week of ïog - the densest and darkest known for several years - and people are still coughing and gasping i'rom the poisonous etiects oí the villainous mixture of gas and ocal dust which has been pumped into their lungs. Business has been more than halt' suspended. The fog was not confined to the streets, but penetrated into warehouses and offices, so that even with gas and candles it was scarcely possible to see to read or writo. Being on the eve of Christmas, this is of course a very busy time, and the doek are full of' ships waiting to discharge their cargoes, but while the fog lasted - from Tuesday to Thursday, and it is hardly gone yet - nothing could be done in this way. Navigation was entiroly stopped on the Thames and the canals. Many omnibuses gave up running, and cabs could only make their way through the towns with the help of a torch-bearer at the horse's head. On the whole, people in the city have : not had a pleasant time of it. To breathe a suífocating and poisonous atniosphere ; to havo to grope about the streets in a darkness more impenetrable than that of night ; and when half t blinded with the stinging vapor, to be i exposod to the onslaught of erratic ve1 hieles, makes up the sum of human : misery. There was a pressure of running trains, as usual, on the railways ; r but most of them were an hour or so , late in starting, and they only crawled l on, with frequent stoppages, amid the f incessant banging of fog signáis, so that they were several hours late in 1 reaching their destinations. The rail3 ways now traverse all parts of the me tropolis, and from the detonations con_ stantly going on the inhabitants might 3 have fancied that they were living in a i bombarded city. There have, of course, - been a groat number of accidents, colf lisions on railways, plate-layers run 3 over while fastening fog signáis on the '' rails, people run down in the streets, people tumbling into the docks and the cañáis, and all kinds oí pit-ialls. zet, after all, the number is less than might have been expected. The fat animáis at the cattle show suffered most, and many had to be killed, while others were removed in a dangerous state. - Fattened up to a point at which they can only just breathe, the wretched creatures have enough to do to live in a pure atmosphere, and the fog simply choked them. Theaters, concert halls and other places of amusement were all filled with the irrepressible mist, so that the stage was dimly seen amid the blaze of gas, and singers warbled, as it were, out of a cloud. Altogether the loss inflicted on London must have amouuted to some hundreds of thousands of pounds. On Thursday the fog began to travel into the country and the midland districts. Nothing makes a great city so helpless as an infltction of this kind.
